Component information including operating parameters for numerical determination of an operation mode of an electronic component mounting operation unit (10) and a change history of the component information are stored in a component information change history storage unit (21). A mounting error occurring during an electronic component mounting operation is detected, mounting error information relating to an occurrence situation of the mounting error is recorded, a transition of the mounting error is displayed on a screen of a display unit (18), and past component information for designated date and time is read and displayed based on the designated date and time so that a correlation between change in the component information and the mounting error can be checked with ease and the component information including the operating parameter can be restored to a proper state. |
